Patented Jan. 19, 1954 .ApplicationAugust 5, 1950, Serial No.-'1 7-7 ,889' 1 This invention relates generally to. scaling members and moreparticularly to leadand-like gaskets for use in conjunction with avertically Vertically adjustable wall closet fittings for supportingwall type water closets utilize a gasket seal between the fitting andadjustable face plate which has heretofore been unsatisfactory. Thegasket is often compressed non-uniformly, resulting in leakage. Thegraphited asbestos. previously used in wall closet fittings quicklydeteriorates and causes leakage. Present gaskets do not penetrate-the,surface pores and other irregularities in the castings forming the faceof the fitting and the adjustable face plate connected thereto,resulting in seepageof water from Tic'laim.

wall closet fitting; and

the connecting joint in connection with the fit- 7 ting. It has beenfound that round gaskets and rectangular shaped gaskets do not penetratethe poresin the'castings thereby permitting seepage of water. It hasbeen particularly difficult to efiiciently and effectivelyseal the jointbetween face plates on vertically adjustable type wall closet fittingsbecause of, the elongated opening in one of the face plates of thefitting.

It is, accordingly, an object of my invention to overcome the aboveandother defects in seals for use withwall-closet fittings and it ismore particularly an object of my invention to provide a gasket for usein conjunction with a wall closet fitting which is simple inconstruction, economical in cost, economical in manufacture, easy toassemble, and efficient in operation.

Another object of my invention is to provide for use'in conjunction witha wall closet fitting a gasket which has sharp edge portions whichpenetrate the vpits, surface pores, and other irregularities in thecastings to provide a perfect seal. 7 V

'Another object of my invention is to provide a groove in a wall closetfitting for disposing a diamond shaped gasket whereby there may be threepoints of sealing contact between the gasket and the bottom and sides ofthe groove.

Another object of my invention isto provide a gasket for use inconjunction with a wall closet fitting which has a high unit linepressure.

Other objects of my invention will become evident from the followingdetailed description, taken in conjunction with the accompanyingdrawings, in which Fig. 1 is a side elevational view broken away on thecenter line of my novel wall closet fitting with my novel gasketdisposed between it and a flange for securing and mounting a watercloset;.

, I has an outwardly directed flange 5 with vertically extending spacedslots 6 on opposite'sides of an elongated opening 8 A groove 9rectanriphery of the opening 8 in the branch 3 of the fitting I.

A vertically adjustable carrier face plate I l with an internallythreaded central aperture l2 l 1 as parallel spaced, verticallyextending slots IS in registration with slots 6 in the flange 5. Theslots 6 in flange 5 are much longer than the slots iii in face plate llso that the aperture [2 in the face plate I I may be adjusted verticallyto different positions in relation to the elongated opening 8 in fittingI. A conventional water closet is secured to the face plate ll through acoupling (not shown) engaging threaded aperture l2 andbolts 40. Bolts l4extend through the slots .6' and l3,the ends of the bolts l4 beingthreadably engaged by nuts 30 to secure the face plate I! into the faceof the flange 5 of the branch 3 of the fitting l in a predeterminedvertical position. A diamond shaped gasket [6 is disposed inthe groove 9in the face of the flange-5 of the fitting l, the opposite side thereofbein'g'engaged by the face of the face plate I I as shown in Fig. 2.Both theface of the flange 5 of the fitting l and the opposing face ofthe face plate I l are normally unmachined cast iron members which havepits, surface pores, and many other surface irregularities. It has beenfound necessary, therefore, to provide a comparatively sharp edgedgasket so that the sharp edge may two members. the" bolt and nutassemblies, :the "sharp edges l l of theflgasketifi{flatten out'as'shownin Fig.4 and the two sidesof'ithe gasket-158' inthe groove its anglesoblique.

In Figs. 5 and 6, I show a modified cross sec tion for my novel gasket.In this instance, one side 2| of my novel gasket 20 is rectangular incross section to fit into the rectangular groove 9 in the face of theflange 5 of the fitting l. The opposite side 22 of the gasket 20converges to a point at 2i and is substantially thesame as one side ofthe diamond shaped gasketshown in Figs. 3 and 4. The sealing action ofthe sharp edge of the gasket 20 shown in Figs. 5 and 6 on the faceof theface plate H is the same as the *sharpedge 'on one side of the diamondshaped gasket l6 shown in Figs. 3 and 4.
